Frozen desserts contained in a microwave active packaging are disclosed. In some embodiments, the microwave active packaging includes a microwave active layer configured to selectively heat the contents of the microwave active packaging. The contents may include a first layer of frozen food, and one or more additional topping layers. When placed into a microwave, the microwave active layer causes the one or more additional topping layers to heat, while the first layer is maintained at or below a freezing temperature. Other embodiments may be described and/or claimed.

Packaging, in particular pre-packaging, for food, comprising a side part. The side part encloses a receiving space for food, and a bottom part. The bottom part is connected to the side part. The connection between the side part and the bottom part includes, at least partially, a releasable connection. The connection between the side part and the bottom part includes, at least partially, a permanent connection. The permanent connection is at least partially movable. The at least partially movable configuration of the permanent connection allows a hinge effect between the side part and the bottom part. The bottom part can be folded down after an at least partially release of the releasable connection.

A product package is disclosed having e a frame part with a recess for a product and a removable inner lining. The frame part includes a base and connected side walls, end walls, and corner parts. The side and end walls each include a first part folded from the base and a second part folded from the first part toward the base. The side and end wall second parts include a cut edge which is fitted into the recess of the package, and the inner lining is fitted on top of the second parts so as to enclose the cut edges. The inner lining also includes an edge section which forms an edge flange extending over top edges of the frame part and a package lid which is arranged to be fastened to said flange.

A food container includes a case including a food storage space, a peripheral flange on tops of the case, a first heat joining area on the peripheral flange, and a first less adhesive area on the first heat joining area; a closure device including a heat sealing layer, an outer layer attached to the heat sealing layer, a second heat joining area on a peripheral edge of the closure device and corresponding to the first heat joining area, and a second less adhesive area on the second heat joining area and corresponding to the first less adhesive area; and a non-sticky after heated lacquer layer disposed between and at the first and second less adhesive areas. After heating the container, the non-sticky after heated lacquer layer is softened and does not adhere to the second less adhesive area to form an exit for releasing both steam and pressure.

To provide a set for microwave heating that is capable of giving a crispy texture to a food by using a heating element configured to generate heat by microwave irradiation and is capable of maintaining softness of a portion in a surface of a food other than a fried face if any, and to provide a package including the set for microwave heating and an outer packaging bag configured to accommodate the set for microwave heating.

Provided is a set for microwave heating, comprising: a tray; a food accommodated in the tray; and a heating laminate comprising a heating element configured to generate heat by microwave irradiation, and a substrate, wherein the heating laminate is disposed in such a way that the heating element side faces the food, and the substrate is laminated on a face of the heating element, the face being opposite to another face of the heating element, the another face being to be or come in contact with the food.

A packaged food product for being heated in an oven or heater includes a container with a food and a lid. The container includes an inwards raised bead at the inner wall of the container near the opening end of the container. The lid includes a recess designed to engage with the raised bead at the inner wall of the container in such a way as to snap-close the container. The food is located in the container.

In summary there is provided in one embodiment a combination of a pan and thermal bag used to maintain hot or cold temperatures of food placed in the pan.

Methods and apparatus for vacuum forming a meat tray using a slurry. The slurry comprises: a moisture barrier comprising AKD in the range of about 4% by weight; a fiber base comprising bagasse; and an oil barrier comprising a water-based emulsion in the range of about 1.5% by weight.

The invention comprises an ovenable packaging structure having an integral one-way valve. The laminate structure comprises an outer layer having a cut line which defines a flap that is separable from the outer layer, wherein the outer layer is adhered to an inner layer having a cut line which is offset from the outer cut line and defines a portion that is separable from the inner layer along the inner cut line and defines an opening into the packaging structure. The adhesive between the layers comprises, in an embodiment, a channel of pressure sensitive adhesive which surrounds both the outer cut line and the inner cut line, wherein the channel of pressure sensitive adhesive defines the perimeter of at least one adhesive-free valve chamber within said channel. The valve chamber comprises at least a portion of the outer cut line and the inner cut line.

A peelable package is described. The package comprises a first sealant layer comprising low density polyethylene and a first contaminant and a second sealant layer comprising polyethylene polymer, such as high-density polyethylene, low density polyethylene, ethylene alpha-olefin copolymer or blends of such, and a second contaminant. The first contaminant and the second contaminant are selected from the group consisting propylene/ethylene copolymer with ethylene content from about 0.1 mol % to about 5 mol %, polypropylene homopolymer, butene/ethylene copolymer and polybutene homopolymer. The first contaminant of the first sealant layer may be the same as or different than the second contaminant of the second sealant layer. Also described are various embodiments of the first sealant layer, the second sealant layer and the peelable seal that is formed between the first sealant layer and the second sealant layer.
